 ## v0.5.4 (Bodacious Boreopterus)
+### Added
+* Changing node configuration values now automatically makes a call to the daemon and updates the configuration there. Changing daemon tokens now does not require any intervention, and takes effect immediately. SSL & Port configurations will still require a daemon reboot.
+
 ### Changed
 * File uploads now account for a maximum file size that is assigned for the daemon, and gives cleaner errors when that limit is reached.
 * File upload limit can now be controlled from the panel.
